Feynman and the Mirror Puzzle

On January 19, 2011, I found an online article about Feynman [1]. This article is a must read for Feynman fans, and I am sure that the person who is not yet a Feynman fan would also become a Feynman fan after reading it. I posted the following comment on it to express my little thought about Feynman.
It's regrettable that the publication of our paper that might supersede Feynman's explanation of the mirror puzzle was made after his passing. It would have been quite pleasant to talk with him about this puzzle.
The mirror puzzle is a fairly famous teaser expressed as: "Why does a mirror reverse left and right but not top and bottom?" Recently I just wrote the essence of our paper on Quora in reply to a question there [2].

That's an interesting question. I think an answer might be that there are no caustics between your eyes and the mirror >:)

Your is the kind of answer I've never heard, and I don't understand what exactly it means.
